To [i1/ZZ whom it may concern,.-

Be itknown that I, GEORGES ERNEST RAI- A NAUD,'a citizen 'of the Republic of France, re-

siding atv 4 4 Rue' du llateau, Vincennes,

Seine,l in the French Republic, commercial traveler, has invented certain new and useful- -Improvements in or Relating' to Boxes for IlluminatedV Signs and Transparencies, of whichthe following is a specification.

-Boxes of the type herein described (intended to receive anyarrangement whatever for illuminating) have vup to the present time at their backs correspondin with the back of* least oneoi their faces. made of a plate of whichthe front s ideexhibits transparentobjects inrelief consisting of' letters or other designs,&c. These objectsin relief have at the plate "spaces or'cham vers in direct communication with the interior; of the box.

,Uideizlsucl constructionwater, dust', vapor,

smoke, 3&0., proceeding from the 'interior of thebox-fpenetrate to-'the spaces or chambers andjldge therein, causing a very ,consider-1 able 'diminution of the transparency of the parts in relief. For this reason it is frequently :necessary to dismount the apparatus to clean vthe chambere'dparts,A which is a notable 1nconvenience.

According-tolthe present invention the an `chambered pieces *or parts are protected lagainst direct communication Iwith the interior of the box,'^ii1 consequence of which all dirt or' other accumulations therein are prevented.k V'Thi'siresult is accomplished by thev interpositionof af supporting-plate between the interior of the box and the designs in relief.

Fig. 5 is afront elevation, and Fig. :6`a corresponding edge view,`- ofl'a'vsupporting-plate for receiving the letter'sho'vn '1n Figs. 1 to 4.'. Fig. Tis a frontelevationshowing the letter applied on theh supporting-plate, and Fig. 8 is a longitudinal section corresponding with Fig. `7. Fig. 9 is a 'front elevation showing a series of letters i applied on 4one 'supporting-plate.A *Fig 10 is a plan view, with parts in section, showinga boxof vwhich oneof thefaces is composed of a plate corresponding with that shown in Fig. 9.

vTheI accompanying drawings illustrate.

The letter for application (represented at Figs. 1 to 4) comprises a plate 1, of which the front face presents some portions in relief, forming the letter H. Corresponding with the parts in relief are hollows or cavities on the back ofthe plate.

In plate 1 are shown two holes 2 and 3 to assist in fixing the letter upon the supporting-plate represented in Fig. 5 and-6. 'Ihe supporting-plate, Figs. 5 and 6, is likewise providedV with two holes 4 andv 5, corresponding exactlyV with holes 2 and 3. On Fig. 5 the position which the applied letter will occupy is traced by aldotted line.

transparent material rendered yopaque by anyconvenient means--for example, by the ter is placed upon the supporting-plate 6 un- 4der the predetermined arrangement'and in such manner that the holes 2 and Scorrespond with those at .4 and 5, andthrcu-gh these holes are passed bolts 7 and 8, the.- pro er pressure being securedby nuts, as 9 10. In addition elastic'washers 11 and 12 arel laced upon the bolts in such manner as to ie between the two united parts-or pieces and to facilitate the tightening.

'The arrangement described indicates 'only the union of a single letter with a supportingplate suitable for .receiving but one letter. In tha-tease the supporting-plate 6 I'will constitute one 'ofthe'faces of a box-suitably equippedwithin for receiving Athe selected illuminating apparatus-electrical, for exp ample-in such manner that the assemblage of this box, thel supp citing-plate, land the ap- 95 plied vletter constitutes a box-fora single letter. A luminous signin such case-mill be made up bya number of similar boxes, according to the number of letters in the sign.

I: Amay install also a collection of applied -letters upon a single sup ortingplaterI'his is'indicated in Fig. 9.

v -he mountingis effected as in the cas'e of a single letter so far as the union of the transparent piece 16 to the 105 box 13-is concerned, as indicated inFig. 1Q'.

f In this gure the box is represented insection,r so as to show the manner in 'which the plate is maintained. Upon the left-hand side ofthis Fig. 10 is represented an arrangeuo The supporting-plate 6 1s, by preference, made of vio Ameans of a bolt and nut.

mentfor holding the plate in a groove, while upon the right-hand side is represented another manner of securing the same object by In Fig. 9 the hatch-lines show the portions which Will be illuminateddthat is to say, the raised portions of the lettersall the other portions of the surface of the transparent plate 6 being rendered opaque by any appropriate means.

Having now fully described my invention, what I claim as new herein, and desire to secureby Letters Patent, ism- 1. A boxV for signs and luminous transparencies having one or more transparent designs in relief upon the front face and hollow upon the back, one of the faces of the boX consisting of a supporting-plate of glass upon the front face of which the back faces ofthe designs"A are fixed to prevent admission of foreign matters to the hollow portions of the de'- signs, the portions of the supporting-plate not covered by the affixed designs being rendered opaque and the portions covered by said designs being left transparent, the parts being combined substantially as shown and l described.

2. In a boxI for signs and luminous transparencieshavmg one or more. deslgns 1n rehef upon the front face and hollow upon the a supporting-plate upon the front face of which the bac faces of the designs are Xed to prevent admission of foreign matters to I the hollow portions of the designs, the comsigns and through corresponding holes in the supporting-plate, and nuts applied upon the inner ends of the said bolts.

3. In a box for signs and luminous translief upon the front face and hollow upon the back, one of the faces-of the box consisting of a supporting-plate ugn the frontV face of which the designs are 4ed to prevent admisporting-plate of bolts 'passing vthrough holes in said plate and in said designs, nuts. upon Witnesses:
